ABSTRACT:
New chlorohydrosilane derivatives having the general formula (I) and preparation method thereof. The chlorohydrosilane derivatives (I) of the present invention which have both Si--Cl and Si--H bonds are prepared by partially reducing chlorosilane of the formula (II) which have at least two Si--Cl bonds with lithiumaluminum hydride. The chlorohydrosilane derivatives (I) of the present invention, which have both Si--H and Si--Cl bonds in a molecule can be advantageously used in preparing various compounds because a Si--H bond enables the hydrosilylation with unsaturated organic compounds, while a Si--Cl bond can participate in hydrolysis or in a reaction with a nucleophilic compound such as Grignard reatent: ##STR1## wherein R.sup.1 is straight, branched, or cyclic alkyl group having 1 to 30 carbon atoms, which can include an aromatic group or heterocyclic group, and R.sup.2 represents chloro group, or straight, branched, or cyclic alkyl group having 1 to 30 carbon atoms, which can include an aromatic group or heterocyclic group.
